Learner categorization has a pivotal role in making e-learning systems a success. However, learner characteristics exploited at abstract level of granularity by contemporary techniques cannot categorize the learners effectively. In this paper, an architecture of e-learning framework has been presented that exploits the machine learning based…

This paper aims to revisit and clarify the term problem context and to develop a theoretical classification of the construct of levels of context use (LCU) to analyse how the context of a problem is used to formulate a problem in mathematical terms and to interpret the answer in relation to the context of a given problem. Two criteria and six…

We present findings from an analysis of the Calculus Concept Inventory. Analysis of data from over 1500 students across four institutions indicates that there are deficiencies in the instrument. The analysis showed the data is consistent with a unidimensional model and does not have strong enough reliability for its intended use. This finding…

In 2008 the Spanish Government announced the inclusion of an oral section in the foreign language exam of the National University Entrance Examination during the year 2012 (Royal Decree 1892/2008, of 14 November 2008, Ministerio de Educación, Gobierno de España, 2008). Still awaiting the implementation of these changes, and in an attempt to offer…

The paper examines systems of validation of skills and experience as well as the main methods/tools currently used for validating skills and knowledge in lifelong learning. The paper uses mixed methods--a case study research and content analysis of European Union policy documents and frameworks--as a basis for this research. The selection of the…

This contribution shows the conditions of a change of prospect in higher education which is based on institutional and policy positioning in favor of the implementation of the devices of Validation of Acquired Experience (VAE) which is used to deliver a whole or components of a qualification (certification) on the basis of the knowledge and skills…

European countries have set themselves 22 specific goals by 2014 to support their long-term vision for vocational education and training (VET). This report is a first step in understanding progress by mid-2012 towards these goals, endorsed in 2010 in the Bruges communique to help achieve the Europe 2020 agenda. Attention has clearly focused on…

Significant momentum exists for next-generation assessments to increasingly utilize technology to develop and deliver performance-based assessments. Many traditional challenges with this assessment approach still apply, including psychometric concerns related to performance-based tasks (PBTs), which include low reliability, efficiency of…

This study examined the teaching practices of 227 college instructors of introductory statistics (from the health and behavioral sciences). Using primarily multidimensional scaling (MDS) techniques, a two-dimensional, 10-item teaching practice scale, TISS (Teaching of Introductory Statistics Scale), was developed and validated. The two dimensions…

The primary purpose of this research was to adapt the Dimensions of Learning Organization Questionnaire (DLOQ) from Watkins and Marsick (1993, 1996) and examine its validity and reliability in a Korean context. Results indicate that the DLOQ produces valid and reliable scores of learning organization characteristics in a Korean cultural context.…

U.S. teacher educators are faced with serious challenges to demonstrate the quality of the graduates they prepare. These challenges are expressed in the country's fixation on accountability and testing. We are witnessing the growth of standardized tests and alternative routes to certification as panaceas intended to solve the teacher shortage…

Despite more than a decade of reform efforts, students continue to experience difficulty understanding and applying statistical concepts. The predominant focus of reform has been on content, pedagogy, technology and assessment, with little attention to instructor characteristics. However, there is strong theoretical and empirical evidence that…

The focus of this report is the Direct Instruction Supervision Code, developed to assess the degree of implementation of the Direct Instruction Follow Through Model. Most of this paper deals with the development, reliability, concurrent validity, and criterion-related validity of the code, which is a classroom observation instrument. The report…

This paper examines the extent to which legitimacy affects program continuation, and focuses on the process by which programs attempt to maintain legitimate status through conformity with the larger environment. Legitimacy is defined as cultural support from a program's larger environment, such as the school district or community. An innovative…

The extent to which evaluation research and psychology share some common objectives, methods and aims for validity is examined. The conventional dichotomy drawn between the two disciplines is seen as spurious and misleading to scholars and practitioners in each area. To demonstrate the proposed synergy between the two disciplines, an integrative…
